No one would mistake Chris Paine for a General Motors shill. In his 2006 documentary Who Killed the Electric Car?, the filmmaker laid out a damning case against GM for unplugging the EV1, the electric vehicle it manufactured in the 1990s and then discontinued in 2003, preferring instead to produce high-margin but gas-guzzling trucks and SUVs. "They were a technological leader, and they fumbled that leadership away," Paine says. Ask him about the U.S. carmaker now, though, and Paine sounds almost admiring. "Their new hybrids are making a difference, and their plug-in technology is a real advance," he says. "GM is making some really good moves now."
